DISPLAY APPARATUS.

SPECIFICATION forming part of Letters Patent N0. 633,650, dated September 26, 1899.

Application led March 9, 1898. Serial No. 673,243. (No model.)

To @ZZ whom it may concern:

Be itknown that I, AUGUST KLUMPP, a citt zen of the German Empire, residing at Munich, in the Kingdom of Bavaria, Germany, have invented certain new and useful Improvements in Display Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for displaying pictorial or other advertisements on tablets which are capable of being intermittently moved, so as to expose to view in succession advertisements of different kinds. In arrangements hitherto employed for this purpose where several tablets with advertisements thereon have been displayed one above another, or side by side, spaces of greater or less width have necessarily been left between the ends or edges of the adjacent tablets, according to the size of the tablets, owing to the said tablets being of the same size or width as the prisms or carriers over which the tablets are caused to travel, and consequently a non-continuous or broken display-surface has been produced.

The object of my invention is to provide means whereby a practically continuous or unbroken display-surface is produced by a combination of tablets, so as to produce a complete picture or device, and which also admits of the picture or character of the advertisements being intermittently changed.

With these objects in view my invention consists in the features and combinations of parts hereinafter described, and pointed out in the claims.

I will describe my invention with reference to the accompanying drawings, in which- Figures l and 2 are transverse sectional views of different embodiments of my improved apparatus. Figs. 3, a, and 5 are respectively a front elevation, a plan view, and asectional view in detail of still another embodiment.

In Figs. l and 2 are represented three sets of tablets a and their carriers, arranged one above another, which tablets may be made of any suitable stiff or practically rigid material-such, for instance, as sheet metal, glass, cardboard, wood, or the like-on which the advertisements or parts to form a picture are provided or mounted. These tablets are riveted or otherwise fixed to endless chains, bands, or the like b, passing around carriers c, mounted on shafts or spindles d, arranged so that. the aXes of the several sets of carriers are substantially equal distances apart, so as to leave clearance-spaces between the carriers. In Fig. l of the drawings I have shown the carriers as being rectangular, this being the simplest form; but they may be circular, triangular, or of any other suitable shape, and any desired number of sets or tablets a may be combined to form a display-surface. The tablets d are of such wid th or length with reference to the distance between two sets of carriers c that when the said tablets are in their displayed position'the edges of the tablets will touch or nearly touch one another,so that visible spaces between the tablets are avoided, and by this improved arrangement a larger display-surface may be provided with a less number of carriers and tablets than heretofore. The carriers c,around which the endless bands or chain-s b pass, may consist of hollow or solid bodies, or they may be open frames, or they may be rectangular disks, as shown in Fig. 2 of the drawings, and they may be rotated or reciprocated by any suitable means, so as to intermittently change the positions of the tablets to display different advertisements or pictures.

Instead of securing the tablets to carriers in the form of endless bands or chains or the like, as hereinbefore described, the said tablets may be pivoted to the diametrically opposite sides or edges of rotary carriers in the shape of pairs of disks, as shown in Figs. 3. 4, and 5, and each tablet be provided on its two faces with different advertisements or designs. Each pair of disks or carriers may be caused to rotate or-reciprocate separately, or several pairs of disks or carriers maybe operated simultaneously, the tablet being of such size that when several sets are arranged side by side or one above another the adjacent edges of the several tablets when brought in to position to display the advertisements thereon will touch or nearly touch one another, so as to form a practically continuous surface. By this arrangement each pair of tablets may be turned on its pivot at each half-rotation of so l 1 IOO the carriers or disks, whereby four different advertisements can be intermittently displayed by each pair of tablets. As shown in said Figs. 3, 4, and 5, the shafts d are disposed one above the other a suitable distance apart, and each shaft is provided near the ends thereof with carriers for the tablets in the form of rectangular or other shaped plates c', at opposite edges of which and between the carriers on each shaft are supported the rods or pivots e, which are adapted to be turned in said plates or in suitable bearings therefor provided on the plates at the said edges. As thus arranged, when the shafts d are turned to bring one set of tablets to view, as indicated at l, Figs. 4 and 5, the other set of said tablets are turned to the position shown at 2, Fig. 5, and both sides of the then verticallydisposed tablets can be easily read or observed. When it is desired to bring the other set of tablets into similar View, the shafts d are turned the extent of one-half revolution, whereupon the rst set is turned into the horizontal position and the second set into the vertical position.

It will be seen from the above that, generically considered, my invention consists in a number of carriers which may be rectangular, triangular, or generally polygonal prisms or star-shaped or circular in cross-section, arranged in 'a parallel series opposite the display-orifice, in combination `vith displaytab lets mounted on belts, aprons, or chains adapt-ed to engage and be forwarded by the carriers, said tablets being so arranged and of such width relatively to the diameter of the carriers and the clearance-space between them that their adjacent edges will meet when the said tablets come opposite the displayopening. This may be effected best, perhaps, by making the width of the tablets greater than the greatest diameter of the carriers, as clearly shown in the drawings. The above holds true whether the carriers are in the shape of polygonal prisms over which the chains or belts carrying the display-tablets travel or in the form of disks on which the tablets are directly mounted.

What I claim, and desire to secure by Letters Patent of the United States, is-

l. In display apparatus, the combination of a number of sets of rotary carriers arranged in parallelism with clearance-spaces between the sets, and with the axes of the several sets substantially equal distances apart, and display-tablets operated to be brought to view by said carriers, the said tablet-s being of such dimensions relatively both to the dimensions of the carriers and the distancesbetwecn the sets of carriers, that each tablet when stationary extends partly across the spaces above and below its carriers, to bring the edges of the several tablets together when the latter are in display positions.

2. In display apparatus, the combination of a number of sets of rotary rectangular carriers arranged in parallelism with clearancespaces between the sets, and with the axes of the several sets substantially equal distances apart, and rigid display-tablets operated to be brought to View by said carriers, the said tablets being of such dimensions relatively both to the dimensions of the carriers and the distances between the sets of carriers,

that each tablet when stationary extends partly across the spaces above and below its carriers, to bring the edges of the several tablets together when the latter are in display positions.

3. In display apparatus, the combination of' a number of sets of rotary carriers arranged in parallelism with clearance-spaces between the sets, and with the axes of the several sets substantially equal distances apart, endless chains or belts passing around the carriers of each set, and display-tablets attached to said belts and operated to be brought to view by said carriers, the said tablets being of such dimensions relatively both to the dimensions of the carriers and the distances between the sets of carriers, that each tablet when stationary extends partly across the spaces above and below its earriers, to bring the edges of the several tablets together when the latter are in display positions.

4L. In display apparatus, the combination of a number of sets of rotary carriers arranged in parallelism with clearance-spaces between the sets, and with the axes of the several sets substantially equal distances apart, and double display-tablets pivotally supported at opposite sides of said carriers, and operated to be brought successively to View by the carriers, the said tablets being of such dimensions relatively both to the dimensions of the carriers and the distances between the sets'of carriers, that each tablet when stationary extends partly across the spaces above and below its carriers, to bring the edges of the several tablets together when the latter are in display positions.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST KLUM Pl.
